Looks like an oncidium to me. Did it bloom?
Here is a bud opening on my Cym Eastern Morning 'Shunshoku.' And taking its time to open. I am really excited because it is an Asian hybrid I've never seen that I bought from Jason Fischer (Orchids Limited). I remember at the big Japanese orchid show a few years ago, I loved a lot of the cym pics online that started with "Eastern." So that's why I bought this.
Cym. goeringii x Cym. lowianum.
